What is the equation of the line, in point-slope form, that passes through the points (-7, -10) and (-6, -8)?
Masja [62]

Answer:

not sure if that is the Answers

The equation of a line is y = mx where m is the slope. That line passes through the origin. If you want it to pass through some point (a, b) you subtract the coordinates like this: y - b = m (x - a). That is the point-slope form, and you can rewrite it in other forms if it is convenient. You may do this with any point on the line.

Determine the values of k for which the equation has no solution:
Bingel [31]

Let's rewrite the equation as


|3x+k| = 1-4 = -3


This should be enough to convince you that the equation has no solutions, no matter which value for k you choose. In fact, the left hand side of the equation is an absolute value, which by definition is always positive, or zero in the worst case.


The equality asks for this quantity to equal -3, a negative number.


A non-negative quantity can never equal a stricktly negative quantity, so the equation has no solutions.

Which are the better statistics to use to compare the team scores? Team A's scores 58 60 62 64 66 68 70 72 74 76 78 80 82 84 86
Alenkasestr [34]

The better statistics that can be used to compare the scores of the two teams are: <u>D. Median and IQR​.</u>

  • The diagram given shows two box plots representing the data of the two team's scores.

<u><em>Box plots</em></u><u><em> displays the </em></u><u><em>5-number summary</em></u><u><em>, namely:</em></u>

  • Minimum data value
  • Maximum data value
  • Median
  • First Quartile (Q_1), and
  • Third Quartile (Q_3)

The Interquartile Range (IQR) of the data can also be calculated by finding the difference between the First Quartile (Q_1), and the Third Quartile (Q_3).

The Interquartile Range (IQR) helps us to determine the variability of the data set.

The median that is gotten from the box pot measures the center tendency of the data.

Both median and IQR are better statistics that can be easily gotten from box plots to compare the team scores.

Therefore, the better statistics to use for comparing the scores of the teams are: <u>D. Median and IQR​.</u>

1/a+1/b=c solve for b how would i do this
olganol [36]

a cheap way to go about it is, let's do away with the denominators, and we'll do so by simply multiplying both sides by the the LCD of all fractions, in this case, that'd be "ab", so we multiply both sides by "ab".


\bf \cfrac{1}{a}+\cfrac{1}{b}=c\implies\stackrel{\textit{multiplying both sides by }\stackrel{LCD}{ab}}{ab\left( \cfrac{1}{a}+\cfrac{1}{b} \right)=ab(c)}\implies b+a=abc \\\\\\ a=abc-b\implies a=\stackrel{\textit{common factor}}{b(ac-1)}\implies \cfrac{a}{ac-1}=b
